Narumi is for the most part a very relaxed person, with a very justified reputation for laziness and perpetual debts; people often will remark the slowness of Narumi to pay his debts. This is even remarked in the alternate world of Raido Kuzunoha the XIV, people will realize Raidou is a different person and will wonder if Narumi has hired another apprentice despite his tight financial position.
However, there are instances where he will forgo his laziness: when informed General Munakata is involved in the Daidouji case, he immediately orders a box of special ammo from Konnou-Ya and willingly marches to investigate a naval base; he is also described as a very competent fighter by the navy officer who witnessed his interrogation and subsequent beatdown.
Also, while lacking any sort of special powers or abilities, he was able to infiltrate the Subterranean Shipbuilding Facility, avoiding the Special Forces soldiers and the demons filling the base, indicating that despite his chronic laziness, he is actually very competent when he wants to be.
Devil Summoner: Raidou Kuzunoha vs. The Soulless ArmyEdit
During the course of The Soulless Army, it is revealed that Shouhei used to be a member of the military before being disillusioned by the corruption of the military. Narumi then founded a detective agency. Shouhei is well versed in the ways of the world, and well connected to various people in the city. In some cases, he has a negative reputation, such as with the Ryuuguu restaurant that he owes substantial money to.
Shouhei functions as a mentor for Raidou, and he takes advantage of his position to have Raidou do all the leg work for him. He still provides valuable assistance to Raidou in the form of advice and guidance. He felt somewhat responsible for General Munakata's actions due to his former connection to the military. He attempted to confront Munakata only to discover that Munataka was possessed by a demon. Raidou Kuzunoha stepped into the conflict and defeated Munakata.
Devil Summoner 2: Raidou Kuzunoha vs. King AbaddonEdit
Shouhei returns as the head of the Detective Agency once again. Now claiming to be a "Modern Man," Shouhei has taken to blending his own coffee and eating nothing but toast for lunch. While preparing some toast, he was almost attacked by a Luck Locust, which Gouto attempted to stop. Gouto prevented the insect's attack, he also ruined Shouhei's pants.
Narumi is being hired by a dame, Akane Narita to find a young man by the name of Dahn. At first wanting to decline, he changes his mind once he saw how much money he would get by doing the job. Both Narumi and Dahn would attempt to collect the Luck Locust cages found throughout the capital during chapter 6.
